Researcher Mary Burke (Mary Bourke) of the Arizona Institute for Planetary Sciences of analyzing the data received from satellites of Mars, said that considerable amounts of water hidden in the large Martian dunes of the northern hemisphere. Frozen water in them, mixed with Martian sand and is probably up to 40-50% by weight.

Terrestrial dunes, containing ice are overhanging cornices, jagged steps, and sharp ridges, which occur due to a combination of designs - ice, snow and sand as well - the action of erosion. The same features found in the dunes on Mars . Even stronger evidence - traces of melting. Both of these features were found in the Martian dunes. Therefore, "If you get to Mars and looking for a source of water, then you should proceed to the nearest large dune," - says the researcher.

The largest sand dune on Mars - Kaiser Dune - has a length of 6.5 kilometers and a height of 475 meters. Maybe - this is the biggest sand dune in the solar system. It is, according to Burke, can contain within more than 500 tons of water, according to Membrana.ru.

Freezing water inside the sand dunes, the author considers the work - this is one more evidence of rapid change of climate of Mars. And, according to Burke, can testify to snowfall on Mars, these sand-shaped ice "mixture" of some 100 thousand years ago that the planets utter nonsense.
